Time Scale and physical time scale
 
Hello every body.
I'm doing a steady-state wind turbine run( rpm=72). I have used Auto-time-scale of 0.02; but it takes long time to converge.
As I know, I may use physical-time-scale but I don't know how to calculate the physical-time-scale.
can anybody help me please?

I don't bother calculating it. Start off with the auto-time scale, then use edit run in progress to adjust it. Make it bigger and see if it seems to help. If not then back off.
